Yeah the R3C is savage ( and has seen off half a dozen gearboxes ) but I've done about 40k kms in a few years and am impressed with its durability. For example: the other day I limiter launched twice in second thinking I was in Rwd but was in max 4wd . I reckon that would be enough to fry most clutches. I do agree the R3C isn't the right clutch for us, but in the right application ( not sure what that is ) I reckon it would be awesome.

Rb26

Eagle rods

Cp pistons

Tomei type b cams

Tomei gears

Mild head porting

Exh manifolds ported

Rotomaster 2860-5

2200cc injectors

120mm intercooler

Adaptronic ecu

Lc-1 wideband

Tomei dumps

Jim berry full Monty clutch

Apexi front pipe

100 cell cat

3.5" exh to x force cannon

B/c valve springs

Mac valve controlling boost via ecu

Best run of 360. On low but left it fat at 350 ish 19 psi

426 kw on 26 psi both united e85

Interestingly was 415 and we cracked airbox (std) and jumped to 426 so I will mod it. Another tuner said couldn't crack 400 with pump (walbro e85) and airbox or that I couldn't go over 24 psi on -5 guess he was wrong

32 airbox always has been an issue. 33 on much better design, dual feed etc.

Good solid result. Be interested to see you go hit the 1/4! Too many '400rwkw -5' GTRs around at the moment that are failing to hit even 124mph let alone the 128-130 they should be, at least half a dozen now :/

10s gonna be EASY for you though me thinks, no fudge with your dessert! :thumbsup:

I'm keeping the airbox but will modify the lower half and sheild the area where the snorkel was, I'm really concerned about traction even with semis although a bit hard she looses traction in 3rd gear on high boost, is this common with 400 plus Gtr ? Thanks for positive comments guys and thanks to jez for a job well done. I had a few issues he fixed , a restrictive tee piece, and failing alternator which actually makes a huge difference to tuning. Again jez is best, the flames are less common now but I'm glad I got a vid of it lol

It's really too bad my old Autronic SMC can't do flex fuel. I'm going to run a similar set up to Scott's with bigger cams. Change of fuel pump (and e85'n my system) would see 400's. So tempting but may have to wait for the next minor round of upgrades.

Great result there Scott! Really has me stoked for my build that will be similar -5 based set up.

It was good experience all said and done and jez is very patient although his initial words of he likes difficult cars came back to haunt with this puppy lol, jez do u rekon leave box for street and switch to pods at track? Wish I bought them with me for testing bugger.

    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
